Connect™ Version 1.5 or later to use the Mini-A to Mini-B USB Cable. If you plug in the cable before
®installing the TI Connect™ software, Windows may assign an incorrect driver for the cable.
INSTALL TI-CONNECT FIRST!!!

 TI-84 Plus or TI-84Plus Silver Edition handheld with fresh batteries and memory archived.
(You wouldn’t undergo major surgery without being at the best you can be, would you?)

How to Archive Your Calculator Memory
When you upgrade your OS, archived items on the receiving unit are not lost. Move items stored in
Random Access Memory (RAM) into the Archived Memory as follows:
1. Press 2nd Mem on your handheld.

3. 1:All…
4. Press next to anything that is
not marked with a to move it into
archived memory, where it will be safe.
You won’t be able to use the item (lists,
variables, programs, etc.) while they are
archived. It is like a fire proof vault!

Press again from this screen
to unarchive them and move them into
RAM.

Update TI-Smartview™ with the New OS

The TI-SmartView™ emulator software gives you a
full functioning TI-84 Plus calculator on your
computer.

To update TI-84 SmartView™ with the latest
OS 2.53MP*, your SmartView software needs to be
version 3.1 or higher.

*If you have a version of TI-84 SmartView™ below 3.0, you
cannot download the Smartview software update from the TI
Web Site. Instead, request your free upgrade by contacting
TI Cares at 1-800-TI-CARES. You will need a photocopy of
your Product Key.

1. If you haven’t yet, go to http://education.ti.com/84 and follow the prompts to get the latest 84 OS and

load that file as well.

If your computer crashes while SmartView is open, it will
revert back to OS v 2.43 when you restart it.

Tip: Click on File > Save Emulator State
while you have TI-84 OS v 2.53MP running
and give it a name, such as MyState2010-03-07.84state,
and click Save. Now if you have a crash while
Smartview is running and it reverts back to OS V 2.43,
you can just reload the Emulator State:
1. Click File > Load File.
2. In the dialog box:
a. Navigate to the folder that contains the emulator state file.
b. Click the emulator state name to highlight it.
c. Click Open.
Welcome to 2.53MP OS!
Notice the new message to access shortcut menus for access to new
features and old favorites when you turn ON your calculator or reset!
Note: Most of the features in the new shortcut menus are available in the
MATH and NUM menus.

The Mode Screen Has Two Pages

As before, the default settings for both Mode pages are all those on the left.

Second Screen:

MATHPRINT CLASSIC – Both Mathprint™ and Classic modes contain
the same new functions, except MathPrint™ mode provides additional
matrix shortcuts from the F3 soft key and displays on the home screen and
Y= editor most inputs and outputs the way they are shown in textbooks,
100
21 3such as  and kx . 24 
k 1
Classic mode displays expressions and answers as if written on one line,
such as or .
Note: If you switch between these modes, most entries typed on the home
screen will be preserved; however matrix calculations will not be preserved
unless you store them. Think of them as images drawn on the screen.

n/d U n/d - selection of fraction output as improper or mixed numbers.

ANSWERS
 Auto displays answers in a similar format as the input.
For example, if a fraction is entered in an expression, the answer
will be in fraction form, if possible.

 Dec displays answers as integers or decimal numbers.

 Frac displays answers as their fractional approximation, if possible.

The Answers mode setting also affects how values in sequences, lists, and tables are displayed.

If any decimal point appears in the expression, then output is decimal. This is a quick way to force
decimal output in AUTO mode.

You can also convert values from decimal to fraction or
fraction to decimal using the FRAC shortcut menu
or the MATH NUM menu.

GOTO FORMAT GRAPH: Selecting YES jumps from the MODE screen to the FORMAT screen.
This handy shortcut puts the FORMAT screen on the user’s radar as a place to check to avoid calculator
glitches, as well as helps support teachers who begin an activity making sure all is highlighted on the left
on both screens. Pressing MODE will return to MODE from the FORMAT screen.

2
STAT DIAGNOSTIC ON OFF - Quickly select the existing option of displaying r and r when
calculating statistical regressions. This is a shortcut to an existing feature (only found in the catalog
under or ) which is placed here for ease of use.

SET CLOCK was pushed to this screen so room could be made for the indicator on page 1.
8 Helpful Tips
ENTER When using scrolling history to select an item, press to be able to manipulate it.
“You must pluck the fruit off the tree before taking a bite.”

 Make these commands your two new friends:

2nd takes you to the end of the line;
2nd takes you to the beginning of the line. These are handy when you may need to scroll horizontally.


ALPHA Use [F1] to quickly access the fraction menu. (You can also can press , press to the NUM menu, press to get , etc. )


 In MathPrint™ mode, you get Super-Sized math templates of old functions as well as new

ones where the screen real estate permits (namely, just the Home Screen and Y= editor);








otherwise these are displayed as inline Classic equivalents in tight quarters (namely, the
expression on the graph screen, WINDOW, TBLSET, TABLE, List entries, etc.)



 Using the soft key in AUTO or FRAC mode with nondecimal numbers gives you
different results than the hard key.
o soft key: [F1] will display as a stacked
fraction in template form where the screen real estate permits (namely, just the
Home Screen and Y= editor); otherwise it is displayed as a “thick bar inline
fraction”, i.e. as , in tight quarters (WINDOW, TBLSET, TABLE, List entries, the
expression on the graph screen, etc.)

o hard key: will display , the usual “thin bar inline
fraction” which gives you the decimal approximation in any mode.

 Look at the screen as you type!
In a math template arrows will appear as guideposts to steer you. Follow them.
For example, if we want , once you are in the exponent are, press .
You may feel the urge to press to move down.
Resist the urge.


 Because of the unpredictability of the height of the expression on the entry line when using

templates in MathPrint™ Mode, entries and answers will not wrap as in Classic Mode;

however, if you watch the screen as you type, you can just break longer calculations into
smaller ones.
or


MathPrint™ Classic

You can also scroll horizontally in MathPrint™ Mode with the left and right arrow keys, but
make sure the expression is on the entry line.

 Notice when you try to access the top row graphing keys and you
are in LOCK (for example, wherever there are list names).
